XQuery 1.0 - 2.3.2 xsd:anySimpleType / xsd:String

Andrew,
anySimpleType is not the same as string. For example, arithmetic can be 
performed on values of anySimpleType, but it cannot be performed on 
strings.

In numbered point 1. in 2.3.2 I wondered why the type is xsd:anySimpleType 

rather than xsd:String.

If it is a text node, then isn't it xsd:String?
